REVERSIBLE EGG-TRAY FOR INCUBATORS.

Specification of Application ined December To (JZ lwhom it may concern.'

Be it known that I, OTTO TETSCHNER, a citizen of the United States,residing at' Burwell, in the county of Garield and State of Nebraska,have invented new` and useful Improvements in Reversible Egg- Trays forIncubators, of which the following is a specification.

This invention relates to egg trays for incubators, the object of theinvention .being to provide an egg tray which may be reversed or turnedupside down in a ready. and convenient manner so that all the eggstherein may be simultaneously turned.

A further object of the invention is to provide an egg ltray composed ofcounterpart sections detachably connected, whereby said sections may beconvenientlycoueggs and removal of the hatched chicks, and in whichprovision 1s also made for 1nnecessitv of uncoupling the tray sections.

A still further object of the invention is to provide a sectional eggtray whereby the eggs may be turned without injury thereto, and which isadapted in either position itoccupies to enable the contents thereof tobe observed and the temperature determined at any time.

The invention consists of the features of construction, combination andarrangement of parts, hereinafter fully described and claimed, referencebeing had to the accompanying drawings,l in which Y Figure 1 is a planview ofv an egg tray embodying my invention. Figs. 2 and 3 are side andend views thereof. Fig. 4 is a vertical longitudinal section on the line4 4 of Fig. 1.

In carrying my invention int-o practice, I provide an egg trayconsisting of two substantially counterpart oblong rectangular sect-ions1 and 2, each comprising an open frame of the form set. forth acrosswhich is stretched a body of woven' wire or other suitable reticulatedor mesh material 3, sustained from outward deflection by cross bars 4.The rectangular frames of the two tray sections have abutting faces 5,and said for detachably coupling them together. The means for thispurpose shown in the present instance consists. of hooks 6 pivoted tothe side and end pieces of one of the sections mms Patent., PatentedAug. 26,1913.

the other section. The hooks and studs are arranged withinv recesses 8and are therefore countersunk, so that the tray maybe inserted, removedand manipulated without liability of the'hooks becoming casuallyunfastened.

The space l'etwcen the foraminous or reticulated walls 3 of the traysections provides a chamber of proper depth for the insertion of theeggsand for the purpose of conveniently accommodating a large number of eggsin a tray Ofminimum size, as well as to prevent possible injury to theeggs when the tray is reversed or turned upside down, the inner faces ofthe side andv end walls of the respective-tray sections are beveled orrounded on outwardly converging lines, as shown at 9, thus allowing thepoints or butts of the eggs to beY received therein and to move in thereversal of the tray without liability of damage thereto.

Each reticulated or foraminous wall 3 is provided with an opening 11strengthened by a reinforcing frame or piece 12 of sheet metal, wherebya thermometer may be supported upon the wall or inserted into the eggchamber for'the purpose of determining the temperature atfany time. Alsofor the purpose of permitting of the insertion andAV removal A of, eggswithout uncouplingv the tray sections, each reticulated o. foraminouswall 3 is provided withy a doorwayll reinforced by a plate 14 to whiclris pivoted a swinging closurel consisting of an open sheet metal framehaving a filling of reticuf lated material, which 'closure 1s adaptedlto engage under a keeper 16 to maintain it in closed position.

1t will be observed that the thermometer openings and doorways arearranged out of respective alinement with each other, so that. allliability of a thermometer dropping through the tray or of the oppositedoorways 4being simultaneously Vand casually "opened will be avoided,while such arrangement also serves as a means by which" the relationshipvof 'the' sides to each other and their relative positions within theincubator at different periods, before and-after turning the eggs, maybe determined.

It will be seen from the foregoing def,- scription that the inventionprovides simple and inexpensive form of tray which` 1' is adapted topermit of the ready passage,

of heat, to be conveniently filled and of the portion of the incubatorin which it is arranged to be Conveniently determined. Also that aconstruction of tray is provided which enables the eggs to be turnedwithout injury, and which provides Yfor the insertlon and removal ofeggs without the necesing provided with a receiving opening yand p adoorway, the openings and doorways of y the respective sections beingarranged in non-registering relation, closures for ,the said doorways,and means for coupling said tray sections together.

In testimony whereof I afIiX my signature 2c in presence of twoWitnesses.

OTTO TETSCHNER.
